When a financial service provider authorised in Ireland by the Central Bank (home state regulator) is operating under a passporting arrangement in another EU member state (host state regulator) the Central Bank, as home state regulator, is responsible for the prudential supervision of that entity.

On that basis, the Central Bank's supervisory responsibilities cover:

Irish-authorised financial service groups and other providers with a head office in Ireland

Irish subsidiaries of financial service groups whose head office is authorised by an overseas regulator
